bug in libgnomecanvas

[Paul Davis <paul linuxaudiosystems com>]

i'd file this in bugzilla, but i can't seem to find a sensible component
for it. the bug is pretty simple, caused by a misunderstanding of what
reserve() does. it was revealed by compiling with _GLIBCXX_DEBUG (as
described here: 

http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug_mode.html)
